The results of measuring stresses in various oxides are considered: NiO, Zr<sub>2</sub>O, Cr<sub>2</sub>O<sub>3</sub>, Al<sub>2</sub>O<sub>3</sub>, etc., studied by different methods. The deflection method is superior to others in measuring stresses in thick oxide scales. However, the coating process brings more errors. In order to eliminate the adverse impacts of coating process, a novel method — Archimedes curve slice moment technique is developed to detect stresses in thick oxide scales on metals for long-term service at high temperature. The experimental principal is illustrated, and the stress formula is derived. Without coating before oxidation, the Archimedes curve slice specimen is oxidized freely at high temperature, and the stresses in oxide scales could be calculated by observing the slice crimping displacement <i>in situ</i> real time during oxidation.
